vue 引用樣式問題

vue 引用樣式問題

app.vue 代碼如下

<template>
  <div id="app">
    <el-button type="primary">主要按鈕</el-button>
    <el-button type="danger">主要按鈕</el-button>
    <el-button type="info" icon="close">主要按鈕</el-button>
    <el-button type="success" icon="edit">主要按鈕</el-button>
    <el-button type="warning" icon="search">主要按鈕</el-button>
  </div>
</template>
<script>
export default {
  data () {
    return {
      msg: 'Hello Vue!'
    }
  }
}
</script>

<style>
</style>

webpack 配置如下

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  resolveLoader: {
    root: path.join(__dirname, 'node_modules'),
  },
  module: {
    loaders: [
      {
        test: /\.vue$/,
        loader: 'vue'
      },
      {
        test: /\.js$/,
        loader: 'babel',
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        loader: 'style!css'
      },
      {
        test: /\.(eot|svg|ttf|woff|woff2)$/,
        loader: 'file'
      },
      {
        test: /\.json$/,
        loader: 'json'
      },
      {
        test: /\.html$/,
        loader: 'vue-html'
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'url',
        query: {
          limit: 10000,
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true
  },
  devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    }),
    new webpack.optimize.OccurenceOrderPlugin()
  ])
}

問題好像就出現(xiàn)在package.json 中 又好像不是？我折騰啦一下午沒有找出問題求助下各位大神，，小弟學(xué)渣

main.js 代碼如下：

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import App from './App.vue'

Vue.use(ElementUI)

new Vue({
  el: 'body',
  components: { App }
})

問題：樣式引用不粗來？ （沒有報）
